How galactic mergers and their stellar survivors shaped our Milky Way

该项目旨在通过开发工具来识别合并后的恒星幸存者，研究与较小星系合并在塑造银河系方面的作用。该项目预计将根据澳大利亚和国际调查数据中最大的搜索结果绘制恒星幸存者的全天地图，并与模拟进行创新性比较，以限制合并的作用。预期成果与澳大利亚天文学十年计划相一致，可以为全球天文学和即将到来的数十亿美元调查合同开辟新的途径。该项目将巩固澳大利亚作为银河系探索新时代领导者的角色，并通过培训澳大利亚人评估复杂的大数据来提供天文学以外的好处。

This project aims to investigate the role of mergers with smaller galaxies in shaping the Milky Way by developing tools to identify stellar survivors of mergers. This project expects to produce an all-sky map of stellar survivors based on the largest search within Australian and international survey data and perform innovative comparisons with simulations to constrain the role of mergers. Expected outcomes are aligned with the decadal plan for Australian astronomy and can open new avenues for global astronomy and contracts for upcoming billion-dollar surveys. The project should cement Australia’s role as a leader in a new era of galactic exploration and provide benefits beyond astronomy by training Australians to assess complex big data.
